dt-bindings: input: awinic,aw86927: Add Awinic AW86938

Add bindings for the Awinic AW86938 haptic chip which can be found in
smartphones. These two chips require a similar devicetree configuration,
but have a register layout that's not 100% compatible.
Still, because chip model is fully detectable via ID register, these
chips can be documnented in the same file.
